Interesting article on DxO about 5D III and D800 resolving power

If you are are trying to compare cameras in terms of resolution (vs sharpness which is not the same thing) you have to compare a full resolution image taken from both cameras of a target shot at the same distance using the same lens (or near equivalent lens which is hard to do). If you're comparing resolution (not sharpness) of two camera/lens combinations, you still have to compare full resolution images shot at the same distance. Accuracy depends on how well the target lends itself to resolution measurements and the methodology used to actually compare the resulting images. If the subject was shot at different distances you can still make accurate comparisons, just not in terms of resolution. --My opinions are my own and not those of DPR or its administration.
